Hi there! Like you, Im also interested in tracing back my roots. My mother is actually a Mejia, Marlyn Mejia from Isabela. His father, now dead, is named Pablo Mejia and I was told that he was originally from Tarlac. Pablo Mejia married my grandma, Margarita Jose. Based on their marriage certificate, Lolo Pablo's parents were from Guillermo and Mejia clans. Perhaps, somehow we are also related and like you, im also interested in making an extensive gen. tree of my family.
